IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 221,937, dated November25, 1879 application filed July 14, 1879.

To all whom it may concern:

Be it known that 1, EDWARD F. Roenns, of Boston, in the county ofSuii'olk and State of Massachusetts, have invented a new and usefulImprovement in Vapor Burners, of which the following is a specification.

The nature of my invention consists in the employment, in connectionwith a perforated va1')orizing-chamber, of a series of adjustable tubesor ductsarranged above the said chamber, by means of which the air ismixed with the generated vapor, as. desired; and also in thecombinati0n,with the above, of an oilchamber having a central opening,and arranged above the adjustable tubes or ducts, for

- the purpose of effecting a more perfect combustion and consequentincrease of heat.

My invention is illustrated in the accompanying drawing, whichrepresents a vertical section of my device.

A represents a saucer-shaped base-piece, which serves as a drip-cup anda support for the burner. From the center of the cup A rises thestandard B, to which is secured the elbowshaped tube piece (J.

F isan annular vaporizing-chamber, co'n' nectcd by the tube 1) with thetube 0, and

provided on its upper side with perforations f f for the escape of thevapor.

E is the oil-chamber, into which oil or other fluid is conducted from areservoir arranged in the usual manner. The oil-chamber E is connectedwith the vaporizing-chamber F by means of the tube G, as shown.

K K represent comically-shaped tubes open at both ends, the largeropenings being at the lower ends and attached to a band or ring, P,fitting loosely on the standard 0, so as to enable them to be turnedupon the standard as an axis when desirable. The said tubes K are placedabove the chamber F, as shown, and when the burner is 1n operation it isdesigned thatthelower openings shall be over the spaces between theperforations f f, in order that the tubes K.

As it sometimes occurs that considerable noise is caused by thecombustion of the vapor, and in order to avoid the same, the tubes K maybe turned so that the lower ends will be over the holes f f when thevapor and air are mixed together in the tubes K. The heat in this casewill not be so great, but is suffi cient'for ordinary purposes.

H is a circular metal plate or button attached to a stem, I, that screwsinto the standard O, by means of which it may be adjusted more or lessnear to the chamber E, as required.

The pipe N, which conducts the oil from the reservoir to the chamber E,terminates in areduced pipe, M, having at its end a small orifice, bywhich means the return of any gas or heated oil or fluid to thefeed-pipe N is pre- In operation, the oil or other fluid. in the chamberF is first vaporized by applying heat to the same in the usual manner.The vapor passes out through the holes f f, and the flame from the samepasses between the tubes KK, and, mingling with the air passing throughthe said tubes, causes a high degree of combustion and great heat. Theflames pass around the sides of the chamber E.

What 1 claim as my invention, and desire to secure by Letters Patent,is-

1. The adjustable tubes or ducts K K, in combination with the perforatedvaporizingchamber F, as and for the purpose specified.

2. The combination of the oil-chamber E, having a central opening, theair ducts K K, and the vaporizingchamber F, substantially as set forth.

3. The combination of the oil-chamber E, the air-ducts K K, and theadjustable disk H, as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

E. F. ROGERS.
